A detailed extensive analysis is made of the solar particle propagation during the long-lasting, complicated November 18, 1968, solar flare event. A thorough analysis is made of the propagation, taking into account (1) the effect of large-scale interplanetary magnetic field (IMF) disturbances on particle populations, (2) the role of long-lasting solar injection processes, (3) small-angle scatterings in the IMF within 1 AU, (4) the influence of a distant (> 1 AU) scattering barrier, and (5) the particle abundance ratios. It is concluded that the solar cosmic rays were the result of a long-lasting solar injection process, the length of the injection increasing for lower-energy particles. The pitch angle propagation characteristics of these particles can be explained by particle propagation in a medium with a long mean free path (?0.3 AU). It is suggested that the techniques of this analysis and the basic conclusions are applicable to many other nondiffusive appearing solar particle events.
